Minimum, maximum and mean annual ground temperatures in permafrost around Abi...
Monitoring of permafrost has been ongoing since 1978 in the Abisko area, northernmost Sweden, when measurements of active layer thickness started. In 1980, boreholes were... -

Number of trunks is the mean number of trunks based on all clusters. Basal area is the mean basal area based on all clusters. The mean diameter for all trees (= total) was... -
Mean cover and frequencies of vascular plant species during three decades aro...
Plant species distributions are expected to shift and diversity is expected to decline as a result of global climate change, particularly in the Arctic where climate warming is... -
Tree line shifts and disturbance events for sites studied in the Torneträsk a...
Aim: Models project that climate warming will cause the tree line to move to higher elevations in alpine areas and more northerly latitudes in Arctic environments. We aimed to... -
Establishment, expansion and regeneration of aspen (Populus tremula) in the T...
In subarctic Sweden, recent decadal colonization and expansion of aspen (Populus tremula L.) were recorded. Over the past 100 years, aspen became c. 16 times more abundant,... -
Initial biomass and biomass change of tundra and forest plants in three herbi...
Recent Pan-Arctic shrub expansion has been interpreted as a response to a warmer climate. However, herbivores can also influence the abundance of shrubs in arctic ecosystems. We... -
Species occurrence and richness of lichen, bryophytes and vascular plants nea...
Little is known about the impact of changing temperature regimes on composition and diversity of cryptogam communities in the Arctic and Subarctic, despite the well-known... -
Tree characteristics, biomass and vegetation cover near Abisko Research Stati...
This study was conducted in the Swedish sub-Arctic, near Abisko, in order to assess the direction and scale of possible vegetation changes in the alpine-birch forest ecotone. We... -

This study investigated the effects of long-term-enhanced UV-B, and combined UV-B with elevated CO2 on dwarf shrub berry characteristics in a sub-arctic heath community.... -
